Welcome to our dedicated page for Nexa Resources SEC filings (Ticker: NEXA), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
Nexa Resources S.A. filings document a foreign issuer with zinc-focused mining and smelting operations in Latin America. Its Form 20-F and Form 6-K disclosures cover consolidated financial statements, earnings releases, CEO and CFO certifications, segment reporting for mining and smelting, and operating data tied to zinc concentrates, by-products and refined zinc metal.
The company's regulatory record also includes mineral reserve and resource updates prepared under NI 43-101, sustainability reports, and financial statement notes on revenues, expenses, exploration and project evaluation, loans and financings, financial instruments, taxes, inventories, property and equipment, leases, asset retirement, restoration and environmental obligations, related parties, risk management and shareholders' equity.
Nexa Resources S.A. reports that operations at its Cajamarquilla zinc smelter in Peru are gradually resuming after an incident on May 13, 2026. Electrolysis lines are fully running, one casting line is producing zinc bars, and the company expects the remaining two casting lines to restart, with the final line targeted by mid-June.
Nexa estimates a 2Q26 production impact of about 7kt of refined zinc, roughly 2% of planned annual production, which it expects to recover in the second half of 2026. Full-year 2026 sales guidance remains unchanged, and the company does not currently anticipate a material financial impact from the incident, though the cause is still under investigation.
Nexa Resources S.A. filed an initial insider ownership report (Form 3) for Vanessa Aita, who serves as Commercial Officer. The filing lists her as an executive officer but does not include any reported transactions or derivative positions, indicating this is a baseline disclosure of her status as a reporting person.
Nexa Resources S.A. is convening its 2026 Annual and Extraordinary General Meetings for June 25, 2026 in Luxembourg, with May 7, 2026 as the record date. Shareholders are asked to approve the 2025 annual accounts, allocate results, grant discharge to directors, reelect nine directors until the 2028 meeting, ratify approximately US$2,300,000 of 2025 board pay and set US$2,310,000 for 2026, and reappoint PricewaterhouseCoopers as statutory auditor through the 2026 accounts. At the Extraordinary Meeting, the board seeks to renew its authority to increase share capital, raise authorized share capital from US$231,942,819 to US$800,000,000, and allow limitation or cancellation of shareholders’ preferential subscription rights, alongside governance-focused amendments to the articles.
Nexa Resources S.A. filed a Form 6-K to report a temporary suspension of operations at its Cajamarquilla zinc smelter in Peru after a fire incident. The fire has been contained and affected areas were evacuated using internal emergency response teams.
There were no fatalities. Four people were injured – one Nexa employee and three contractors – and all are reported in stable condition. Portions of the smelter infrastructure were damaged, and the company is working with relevant authorities while investigating the cause and assessing when operations can resume.
Based on information available at this time, Nexa states that it does not anticipate a material impact from this incident. Cajamarquilla is described as the largest zinc smelter in the Americas and is part of Nexa’s integrated network of five polymetallic mines and three zinc smelters in Peru and Brazil.
Nexa Resources S.A. filed a Form 6-K as a foreign private issuer, mainly to furnish CEO and CFO certification documents related to its first quarter 2026 disclosures. The filing includes full certification forms signed on May 6, 2026 by President and CEO Ignacio Rosado and Senior Vice President of Finance and Group CFO José Carlos del Valle.
The company explains that it relies on an exemption under Part 4 of National Instrument 71-102 for foreign issuers, so references to “interim MD&A” in these certifications instead refer to Nexa’s Earnings Release dated May 6, 2026. This filing is therefore an administrative step confirming management’s responsibility for the accuracy of those interim disclosure materials.
Nexa Resources S.A. reported a much stronger first quarter of 2026, with net revenues of US$888 million, up 42% year-over-year, and net income rising to US$118 million. Adjusted EBITDA more than doubled year-over-year to US$283 million, delivering a margin of 31.8% as higher metal prices, especially silver and zinc, and increased smelting volumes lifted profitability.
Operating cash flow before working capital reached US$308 million, though seasonal working capital outflows drove free cash flow to US$(126) million. Even so, net debt/LTM Adjusted EBITDA improved to 1.59x, and total liquidity stood at US$396 million in cash and investments, or US$716 million including an undrawn revolving credit facility. Zinc mine production rose 18% year-over-year to 79 kt, while smelting zinc sales increased 13% to 147 kt, supported by record zinc output at Aripuanã and ongoing recovery at Brazilian smelters. Management reaffirmed 2026 guidance for production, costs, and CapEx.
Nexa Resources S.A. reports strong unaudited results for the three months ended March 31, 2026, with net revenues of 888,321 and net income of 118,051, both much higher than the same period in 2025. Basic and diluted earnings per share rose to 0.67 from 0.09, as higher metal prices and volumes lifted gross profit to 272,146 from 126,563. Adjusted EBITDA reached 282,627, driven mainly by the mining segment. Despite the profit jump, net cash used in operating activities was 55,588, and total loans and financings increased to 1,768,133, while shareholders’ equity grew to 1,447,578.
